摘要：目的研究甘肃8个主产县红芪药材的傅里叶变换红外光谱(FT-IR)指纹特征,为不同产地红芪的鉴别应用提供依据。方法采用FT-IR技术,采集甘肃省8个红芪主产县110批红芪样品在4000~400 cm-1范围内的指纹图谱数据,对指纹图谱的共有模式进行光谱解析,对8个主产县红芪的FT-IR指纹图谱进行相似度分析,比较不同主产县红芪的FT-IR指纹特征。结果 8个主产县红芪FT-IR指纹图谱的平均相似度大小排序为宕昌>礼县>西和>武都>漳县>岷县>陇西>渭源,陇西、渭源红芪与其他产地的样品差异较大;陇南地区(宕昌、礼县、西和、武都)红芪的FT-IR指纹图谱较为相似,平均相似度较大,而定西地区(漳县、岷县、陇西、渭源)红芪的FT-IR指纹图谱较为相似,平均相似度较小;每个主产县红芪的FT-IR指纹图谱均具有显著、唯一的FT-IR指纹特征。结论根据FT-IR指纹特征能够实现甘肃8个主产县红芪药材的鉴别应用。
Objective To study the FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province;To provide references for identification and application of Hedysari Radix in different producing counties.Methods FT-IR fingerprints of 110 batches of Hedysari Radix from 8 producing counties in Gansu Province were collected in the wave number range of 4000–400 cm-1.The common pattern of the fingerprints were analyzed,and the similarity analysis were used to analyze the FT-IR fingerprints of Hedysari Radix from 8 producing counties.The FT-IR fingerprint characteristics of Hedysari Radix from 8 producing counties in Gansu Province were compared.Results The rank of average similarity of FT-IR fingerprints of Hedysari Radix from 8 producing counties was Tanchang County>Li County>Xihe County>Wudu District>Zhang County>Min County>Longxi County>Weiyuan County,and Hedysari Radix from Longxi County and Weiyuan County were very different from other producing counties.The FT-IR fingerprints of Hedysari Radix from Longnan City(Tanchang County,Li County,Xihe County and Wudu District)were similar,and the average similarity was relatively high;while that from Dingxi City(Zhang County,Min County,Longxi County and Weiyuan County)were similar,and the average similarity was relatively low.Hedysari Radix from every producing county had a significant and unique FT-IR fingerprint characteristic.Conclusion The identification and application of Hedysari Radix from 8 producing counties in Gansu Province can be realized according to FT-IR fingerprint characteristics.
